Answer:
Water
Explanation:
Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.
In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.

The service sector jobs that have increased in importance differ in some significant respects from traditional manufacturing jobs. Service industries have a higher incidence of part-time and temporary workers, rely more on unpaid overtime and make greater use of flexible work arrangements.

A decomposition of labour compensation growth over 1976–79 to 2001–05 resulted in findings that were generally similar to those derived from the shift-share analysis of productivity growth.
